Liverpool have conceded a grand total of 13 goals from set-pieces in this season's Premier League - only Norwich (14) and Bournemouth (15) have let in more.

But when you take the total goals each team have conceded and look at the percentage which have come from set-piece situations… well, then you get this table:

Proof that more than 40% of the goals scored against Liverpool are scored via a set-piece - more than any other top-flight team.

When a team has an issue from set plays, the assumption is always that they struggle in the air. Sure enough, many experts have suggested Klopp's Liverpool side are too small and don't win enough headers.

HOWEVER…

There are only three sides in the division who win more of their aerial duels:

1 Aston Villa

53.2 %

2 Man City

3 Arsenal

52.5 %

4 LIVERPOOL

Which suggests that the problem is not with the size, height or heading ability of Liverpool's defence… it's with their organisation and concentration.
